Detailed description of the invention

Hinge 1 includes the first hinge fraction 2, and this first hinge fraction has and is securable on Furniture Body or household electrical appliance Bearing 3, hinged installation hinge arms 4 on this bearing.For this tectonic axis 5 on lobed socket 3, axle 5 is rotatably pacified Hinge arm 4.Hinge can also be rotatably mounted by having the joint institution of two levers on the first hinge fraction Arm 4.

It addition, hinge 1 also includes the second hinge fraction 6 can being fixed on door or trap.For this second hinge fraction 6 Having plate 7, this plate has installing hole 70.On the second hinge fraction 6 also additionally structure by two sidewalls 8 around cup-shaped recess 9, to accommodate the end section of hinge arms 4.The space 13 in the front that may be inserted into hinge arms 4 is set in the region of this recess 9.

As in figure 2 it is shown, in order to the first hinge fraction 2 is arranged on the second hinge fraction 6, first hinge arms 4 towards recessed Mouth 9 moves, and is wherein configured with spigot surface 10 on relative sidewall 8, is configured with the recess 11 of channel-shaped on this spigot surface.In hinge Being provided with round and smooth projection 12 on relative side 16 on chain arm 4, wherein when inserting hinge arms 4, projection 12 is inserted into In channel-shaped recess 11.

In hinge arms 4, additionally being structured with two prominent laths 17 on front, wherein this lath 17 is inserted into In the space 13 of the second hinge fraction 6.

It is L-shaped that hinge arms 4 is configured to side, and includes tabular end 15, is rotatably mounted ratchet on end 15 18.Being maintained on axle 19 for this ratchet 18, its axis 19 is configured on end 15.Ratchet 18 is connected with pusher dog at this, by Ratchet 18 can be moved in this pusher dog.

Figure 3 illustrates the hinge arms 4 installation site on the second hinge fraction 6, wherein pusher dog 20 can be along leading Offseting to face 14, wherein spigot surface 14 is configured on the sidewall 8 of the second hinge fraction 6.In hinge arms 4, end 15 is inserted Time, pusher dog 20 is shifted by along spigot surface 14, and wherein pusher dog 20 moves towards end 15, thus ratchet 18 overcomes the power of spring and inclined Turn, as shown in Figure 4.Pusher dog 20 almost has passed past spigot surface 14 and on the second hinge fraction 6 in the diagram, and is positioned at locking Position somewhat before, wherein after this latched position upper poking claw 20 is locked in spigot surface 14.Position before locking is somewhat In, ratchet 18 is arranged, so that visually can know well highlightedly relative to the adjacently situated surfaces 22 in hinge arms 4 Do not go out hinge arms 4 not lock on this second hinge fraction 6.In the diagram, in order to more intuitively cut away part hinge arm 4 at this.

Pusher dog 20 and spigot surface 14 is not had to there is a risk that, if such as hinge arms 4 is difficult to be inserted into the second hinge In part 6, then in locking process, ratchet 18 is the most accurately held on rib 140.Although hinge 1 seems to be locked in In this position, but this ratchet 18 can upper once shake time rebound from this rib 140, and hinge 1 unlocks.This state also by It is referred to as " spurious lock ", and can result in and propped up.

In order to reliably avoid this " spurious lock ", spigot surface 14 has certain length, which ensure that if ratchet 18 Can deflect into below the contact surface 141 of hinge fraction 6, then this ratchet 18 is discharged to lock by pusher dog 20.

Herein relate to one " close and postpone ".This " close postpone " can apply to all types of wherein there may be During the clamping of " spurious lock " connects, namely parts to be clamped the most correctly are locked.

In Figure 5, hinge arms 4 continues to move in latched position, so that pusher dog 20 leaves spigot surface 14 now And it is adjacent to locking with spigot surface 14.It can be seen that pusher dog 20 is integrally constructed with ratchet 18 phase by coupling part 21, and The most together it is rotatably mounted around axle 19.Being adjacent to locking by pusher dog 20 and spigot surface 14, ratchet 18 is again positioned at table In face 22, the most in Figure 5 in order to more intuitively cut away part hinge arm 4.

Figure 6 illustrates the hinge 1 in the latched position after being in installation, wherein ratchet 18 is basic and in hinge arms 4 Adjacently situated surfaces 22 arrange with flushing.In this position, present hinge 1 can open and close around axle 5.

If occur in that mistake when hinge arms 4 is arranged on the second hinge fraction, and pusher dog 20 is maintained at locking Position somewhat before, as shown in FIG. 7, then ratchet 18 is arranged highlightedly with respect to surface 22, such as institute in Fig. 4 above Show.If forgetting pusher dog 20 to move to latched position when mounted, the position of Fig. 7 is closed hinge 1, then this is all right Make up, because ratchet 18 is in prominent position and can be pressed by the contact surface 23 on bearing 3 when hinge is closed.

Lobed socket 3 is moved corresponding to the arrow of Fig. 7 relative to the second hinge fraction 6, so that corresponding to Fig. 8 Contact surface 23 move towards prominent ratchet 18, and according to Fig. 9, described ratchet 18 is pressed in latched position.By hanging down Directly ratchet 18 applying on the direction of contact surface 23 power, what hinge arms 4 was last is partially inserted into the second hinge fraction 6 Recess 9 in, and leave spigot surface 14 at this by pusher dog 20 and lock.

If thus pusher dog 20 locks failure when mounted, then at the latest when closing for the first time hinge 1 ratchet 18 just by It is forced to move to latched position, thus reliably Automatic-clamping hinge 1.Can no longer carry out voluntarily and less desirable unblock. Thus significantly improve locking reliability.

Figure 10 illustrates the hinge 1 in latched position.

The most only being provided with a ratchet 18, it is rotatably arranged by a pusher dog 20.Spine This shape of pawl 18 and pusher dog 20 and layout can change.It can in addition contain arrange multiple ratchet 18 and pusher dog 20.Except list Outside hinged hinge, it would however also be possible to employ utilize four hinged or seven hinged hinges that locking mechanism of the present invention constructs or utilize other The hinge of motion principle.

In addition to visually indicating the locking of reality, it is also possible to indicate locking in audition.Such as swing in hinge arms When pusher dog is locked under contact surface 141 simultaneously, produce perceptible " click sound ".

Visually indicating when installing hinge and be difficult to a certain extent, audible indication the most additional is complete It is very favorable for becoming fully locked.
